A small sampling of pneumatic valve small product big use

sampling pneumatic valve is used to get samples by the media in pipeline or equipment of the pneumatic valve, in many need to frequently on the occasion of medium for chemical analysis of samples, will use special sampling pneumatic valve. According to the sampling principle of work or performance is different, when sampling pneumatic valve is mainly divided into three categories, including double open the pneumatic valve, pneumatic valve flange shim and sampling pneumatic valve with insulation jacket.
double open the pneumatic valve, pneumatic valve is more commonly used sampling is usually composed of two connected pneumatic ball valve, its characteristic is safe and stable sampling. In the process of sampling, the first shut down the double open near the equipment and pipeline in pneumatic valve A pneumatic valve, and then open B pneumatic valve, let the medium into the space between two pneumatic valves, pneumatic valve, pneumatic valve opens and closes B A place sampling vessels in sampling mouth sampling medium.
